Catching Throwable in non-framework code in PutTaskRequestContent

**Affected version:** HEAD

**File:** `maven-resolver-transport-jetty/src/main/java/org/eclipse/aether/transport/jetty/PutTaskRequestContent.java:246, 298`

```java
} catch (Throwable t) {
lockedSetTerminal(Content.Chunk.from(t, true));
}
```

Catches `OutOfMemoryError`, `StackOverflowError`, `InternalError`, etc. These should propagate. Wrapping them as terminal chunks converts fatal JVM errors into regular failure conditions, making them invisible to diagnostics.

Originally reported in #1944.

Start in maven-resolver-transport-jetty/src/main/java/org/eclipse/aether/transport/jetty/PutTaskRequestContent.java at lines 246 and 298, and read the surrounding terminal-error handling. Verify the behavior for fatal JVM errors, then run the relevant transport tests; done means those errors propagate instead of being converted into terminal chunks.
